Deci-

Deci- (symbol d) is a decimal unit prefix in the metric system denoting a factor of one tenth. Proposed in 1793 and adopted in 1795, the prefix comes from the Latin decimus, meaning "tenth". Since 1960, the prefix is part of the International System of Units (SI). Its most frequent use, however, is in a non-SI unit, the decibel, used to measure sound intensity (relative to a reference) and many other ratios.
